The library contains variables and functions intended to make it simple for your program to provide detailed error message failure on the part of a library call in the usual format. A locale-specific error message string is not produced by this function. Depending on the compiler and platform used for development, strerror generates error strings, and converts a string of error messages to the error number in errnum.Įrrno values with proper errnums are required. The C library calls char *strerror(int errnum), which produces a reference to a string comprising of the error message, and searches an internal array for the error number errnum. If this occurs, the function returns -1, and your code must rely on our trusty errno to figure out what went wrong and perhaps emit an instructive error message. As soon as your program tries to reach the operating system, something goes wrong. Error message was:Īt (Activity activity, IDictionary`2 inputs, WorkflowInstanceExtensionManager extensions, TimeSpan timeout)Īt (Activity workflow, IDictionary`2 inputs, TimeSpan timeout, WorkflowInstanceExtensionManager extensions)Īt .DefaultDiscovery.System errors do occur. Task invocation failed with error code -2130771925. Unexpected DiscoveryResult.ErrorData type.

If the second one fails you still have a certificate issue. If this works it should show up in SCOM as long as your Run As accounts are setup properly. Winrm enumerate -username: -password: -r: -auth:basic -encoding:utf-8 If this works try running without the -skip* options: Winrm enumerate -username: -password: -r: -auth:basic -skipCACheck -skipCNCheck -skiprevocationcheck Try running the following command from a command prompt on the SCOM server. ![]() If you can telnet then we know port 1270 is open properly. If you have feedback for TechNet Subscriber Support, contact you telnet successful to port 1270 on this server? It should connect but not return anything if successful. Please remember to mark the replies as answers if they help. Once complete, restart the agent by running the following command: /opt/microsoft/scx/bin/tools/scxadmin -restartįor more detailed information, we may refer to: We can also change the hostname and domain name on the certificate by using the -h and -d switches, as in the following example: /opt/microsoft/scx/bin/tools/scxsslconfig -f -h -d We can view the basic details of the certificate on the UNIX or Linux computer by entering the following command: openssl x509 -noout -in /etc/opt/microsoft/scx/ssl/scx.pem -subject -issuer -dates When the Discovery Wizard deploys an agent, it retrieves the certificate from the (linux) agent, signs the certificate, deploys the certificate back to the agent, and then restarts the agent. I noticed that "And also unix team confirmed that, firewall is disabled on the servers.", have we confirmed this? We can telnet to this port from another computer to see if port 1270 can be reached. Please help, what can we do from scom side to fix this.įor unix/linux computers, we need to open port 1270. The servers in the resource pool have not been configured to trust certificates signed by other servers in the pool.Īnd also unix team confirmed that, firewall is disabled on the servers. ![]() The destination has an invalid certificate, e.g., its common name (CN) does not match the fully qualified domain name (FQDN) used for the connection.Ĥ. The destination certificate is signed by another certificate authority not trusted by the management server.ģ. The destination computer is unreachable (because it is down, or due to a firewall issue).Ģ. WinRM firewall exception for public profiles limits access to remote computers within the same local subnet.ġ. Verify that the specified computer name is valid, that the computer is accessible over the network, and that a firewall exception for the WinRM service is enabled and allows access from this computer. So i am trying to discover the unix/linux computers by using root credentials, but while discovering, below error is coming. Some UNIX/linux servers are newly built, and we need to put those servers under Monitoring.
